I was wondering what kind of time i can expect with the T51Kai in the 1320? I also have a OS Giken twin plate and a Kazza Dif. I am running 15lbs of boost and the fuel ratio is about 13:1.

Thank you!

At that a/f ratio, you might as well plan on not running for very long. That's very lean !

DiaperBoy

It only goes that lean at the topend.......that's why i want to get a standalone.......i have the Power FC now and i can't seem to get it to work with the bigger injectors?

DiaperBoy

aaaahhhhh...i typed the wrong info....i ment it was a 15:1.....oops...but i still want to get a standalone...

Roy Johnson, Jr

DUDE, I'd get that car to a dyno quick 15:1 is insane

What size injectors are you running (trying to)?

how do i find my a/f ratio??? im new to the rotary scene.

What wideband are you using for your A/F? It sounds like your O2 sensor is dead. When they start going bad they start reading leaner and leaner.

Yellow RX-7, the way you test for A/F is with a wideband O2 setup. If you car is stock or only has a few mods there is no real reason to test unless you are curious. Running a standalone ECU will cause the need for a wideband O2 since you completely control A/F.

thanks for clearin that up for me styk. one more thing though, what does lean mean?

sickboy

WTF!? that bitch shouldnt RUN long enough at 15:1 for you to be able to tell us about it. you generally dont wanna go past 12:1 max in the top of the revs.

This all sounds a bit fishy to me....
